ANTONIO ROSS, or UTIGA, NEW YORK.

' GRATER.

To all whom it may concern:

Be it known that I, 'ANToNIoRos's, a citi-. zen of the United States,residing at Utica, in the county of Oneida and State of New York, haveinvented certain new and useful Improvements in Graters; and I' dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to new and useful improvements in graters, andhas for its principal object to provide a device which is particularlyadapted for grating cheese or similar material.

Another object of the invention is to provide a device havinginterchangeable blades which may be used for grating or for cutting thinslices at the desire of the user. I

A further object of the invention isto provide a novel method of feedingthe material, which is beinggrated, against the cutter blade to insure auniform product. I

A still further object of the invention is to provide a novel means forsupporting the material which is to be grated or sliced and also forremoving the samefrom its support- With these and other objects in view,the invention consists in the novel combination and arrangement of partswhich will be fully set forth in the following specification andaccompanying drawings, in which,

Referring now to'the drawings by characters of reference, the numeral 1designates as an entirety the frame of the device which 'ingSpecification of Letters Patent. PatentedMay-fzg, 1917, Applicationfiled July 9, 1914. Serial No. 850.003.

is supported on the legs 2 carrying the'upwardly extending side pieces3. These side pieces 3 areheld in spaced relation by means of the itransversely extending member t which supports the bottom 5. A suitableangle bracket 6 is provided and is arranged to form a brace between themember 4: and the bottom 5 hereinbefore referred to.

A suitable inclosure 7 is secured to the side 3' and is providedzwiththe horizontal opening S-aS clearly shown in Fig. 4. A suitable plate 9is secured'to the upper side of the closure 7 and supports the sleeve10, the use of which will appear as the description proceeds. suitableU-shaped member designated generally by the numeral 11, is arranged tobridge the space between the portions 3 as clearlyshown in Fig. l.

The inner faces of the walls 3 are beveled inwardly as at- 12 and arearranged to conform to the shap'e of the material which is beinggratedExtending longitudinally of the reduced-edge of the walls 3 are the rods'13 which are arranged to form guides cooperating with the sleeve 10hereinbefore referredito. 1

At the end of the .walls 3 opposite the closure 7 are provided theplates14: having the ears 15 formed thereon. These plates -are,provided withthe inturned flanges 16 which are curved to true of the hood 17 which isprovided with conform to the curvathe reinforcing members 18, withinwhich the follower, which will be more fully hereinafter described, isarranged to fit.

A suitable door 19, which comprises the body portion 20 carrying thereinforcing rods 21, is provided and the free ends of the reinforcingrods terminate in the ears 22, which are arranged to cooperate with thecars 15 to receive the pin 23 and thereby removably secure the door inplace. posite terminals of the rods 21, are riveted or otherwise securedas at at to the upper flange 25 of the door and the ends of the flangeare The opextended so as to cooperate with the remainears 15 in holdingthe door in place. The rivets or bolts 24, which support the upper endsof the rods 21in place against the flange 25, project through the ears26 which carries at its inner end the disk 30. This are formed on thebearing members 27 'hav- I ened as at 49. These bolts are held disk isprovided with the enlarged nut 31 and has formed near its periphery aplurality of apertures 32, through which the bolts 33 carrying the nuts34, extend. These bolts 33 are arranged to support the plate and thenuts 34 are arranged to hold the said plate 35 in spaced relation withthe disk 30 hereinbefore referred to. The forward ends of the bolts areextended as at 36 and are arranged to support the gratingdisk 37 havinga plurality of apertures 38 formed therein. These apertures 38 areprovided with the outturned roughened edges which are to be used for anobvious purpose. The opposite end of the shaft 29 is externally screwthreaded and arranged to receive the end 38 of the crank 39, by means ofwhich the disk 30 is rotated.

Slidably supported on the rods 13 is. a transverse bar 40 having acentral aperture through which the rod 41 is arranged to project. Thisrod 41 is provided with a threaded extension carrying the nut 42 whichcooperates with the U-bolts 43 in supporting the disk 44 in properposition. A suitable stop 45 is carried by the rod 41 and is arranged tolimit the movement of the bar 40 with relation to the bar 41. Formed atthe free end of the bar 40 are the flattened extensions 46 through whichthe bar 13 extends. One of these extensions 46 is provided with a groovein which the controlling lever, which will be more fully hereinafterdescribed, is operatively mounted. A reduced extension 47 is formed onthe grooved end of the bar 40 and is arranged to form a connection forthe spring as will appear hereinafter.

Extending through the disk 44 are a plurality of bolts 48 having theirends sharpfirmly in place by means of the nuts 50 and are arranged toslidably hold the disk 51 in position on the disk 44. This disk 51 isconnected as at 52 to the free ends of the arms of the U-shaped member53, the bight portion of which is extended through the lever 54 which ispivotally mounted as at 55 to the extension 56 carried by the disk 44.The opposite terminal of the lever is provided with a suitable knob 57by means of which the operation of the lever is controlled. This disk 51is arranged to form an ejector plate by means of which the materialwhich is being grated is forced from the ends of the supporting members48 upon operation of the knob 57.

A suitable controlling lever 58 is pivotally secured as at 59 to one ofthe sides 3 and is provided at its free terminal with the grippingelements 60 adjacent which is the longitudinal slot 61 through which thegrooved end of one of the reduced extensions 46, projects. A suitablecoil spring is pivotally connected to the extension 47 as illustrated inFig. 1, and said spring extends over a grooved pulley wheel 62 and intothe slot 63 formed in the tubular member 64. This tubular member 64 isarranged to form a guide for the spring to prevent the same frombecoming accidentally displaced. The opposite end of the spring isextended through the tubular member 64 and threaded on to the threadedend 65 of the cylindrical member designated generally by the numeral 66.This cylindrical member is pro vided opposite its threaded end with theenlargement 67 through which .the bar 68 forming the gripping member bymeans of which the-device is rotated, extends. This cylindrical member66 extends through and is rotatably mounted in the sleeve 69 which isheld in the end of the tubular member 64 as illustrated in detail inFig. 9.

When it is desired to use the device in slicing rather than grating thematerial upon which it is in operation, the cutter blade des ignatedgenerally by the numeral 70, as illustrated in Fig. 8, is substituted inplace of the grating blade 37. This cutter blade is provided with a pairof radial slots 71 with which the removable blades 72 cotiperate. Theseblades 72 are provided with the edges 73, which when rotated, arearranged to slice the material upon which the device is operating, inthin slices.

The modified form of cutter blade, which is designated generally by thenumeral 78, comprises a suitable disk 79 having secured thereto the rim80. This disk 79 is provided with a slot 81 near its center whichcooperates with the slot 82 in forming the central bar 83. A suitablecutter blade 84 is arranged to be secured to the disk and said blade isprovided with beveled edges which cotiperate with the slots 81 and 82 inslicing the material in the cutter. The usual holding or securing posts85 are provided and carry the usual faces 86, by means of whichthecutter blade is held in spaced relation with the rotary member 37hereinbefore described.

In order to hold the follower hereinbefore described in its rearmostposition, there is provided a suitable latch designated generally by thenumeral 74 which comprises the pawl 75 which is pivotally secured as at76 to one of the side walls 3. This pawl 7 5 is provided at its rear endwith the-knob 77 by means of which the device is controlled, and at itsforward end with a suitable hook hook member which is arranged to hookover the transverse bar 40 to hold the same against movement. A suitablestop is also provided and arranged to cobperate with the latch member 74to limit the movement of the follower.

It will be apparent from the foregoing that in use the material which isto be grated or sliced, is placed in the space between the follower andthe blade. The pawl is then released and the follower permitted, underthe influence of the spring, to slide forward so that the material uponwhich the device is to operate is forced against the grating or slicingblade. The crank 39 is then rotated and it will be apparent that theroughened portion of the grater will engage the material upon which itis to operate and thereby cause the same to be finely ground and auniform product is thereby obtained.

While in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that such changesmay be made in the combination and arrangement of parts as will fallwithin the spirit and scope of the invention as defined in the appendedclaim.

Having thus described my invention, I claim:

A grater of the character set forth including a support, a troughmounted upon said support, a pair of guides arranged on the upper edgesof said trough, a cutter mounted at one end of the trough, a followerslidably mounted within the trough, means for supporting said followerto permit the same to move longitudinally within the trough, atransverse bar slidably mounted on the guides and connected to saidfollower, one end of said bar projecting beyond the sides of saidtrough, a lever provided with a slot intermediate its ends, said slotconnecting said transverse bar of the follower with the lever, a rod tohold the follower in its rearmost position, spring means to exert pullon the follower to urge the same toward the cutter, means to ad just thetension of the spring to urge the follower toward the cutter, and meansto limit the movement of the follower in its sliding movement in thetrough.

In testimony whereof I aflixmy signature in presence of witnesses.

ANTONIO ROSS.
